MACHINE FOR MAKING SHEET-METAL BARRELS.

Specification of Letters Patent.

Patented Mar. 18, 1913.

Application filed April 12. 1909. Serial No. 489.250. Renewed November 11. 1912 Serial No. 730,787.

To (1U whom it may concern Be it known that I. JOHN H. KlLLlOX. a citizen of the United States. residing at Chicago. in the county of Cool; and State of Illinois. have invented certain new and useful Improvements in Machines for Maklowing is a specification.

The principal object of my invention is to provide a machine for shaping the side walls for sheet metal barrels.

Another object is to provide a machine for corrugating such sheets.

Still "another object is to provide a machine for corrugating such sheets and at the same time giving them a bilge shape.

Still another object is to provide means for successfully detaching the sheets from the machine after they have passed through the same. I j

A still further object is to provide suitable feeding mechanism to work in conr bination with such a machine.

Other objects of my invention will be more readily made apparent in the following specification and claims taken in connection with the accompanying drawings.

\\'ith these objects in view. I have illustrated in the accompanying drawings a specific embodiment of my invention which is atpresent the form preferred by me. My

invention however. consists of the combination of elements stated in the appended claims.

Referring to the drawings-Figure 1 is a front elevation of my machine. Fig. '2 an end elevation thereof. Fig. is an end elevation of one-of the rolls of the machine. Fig. l is an axial section of the same. Fig. 5 is a section of the feed table taken on the line 5 in Fig. 6. Fig. 6 is a secti n of the same table taken on the line 6 in Figs. 3 and T. Fig. 7 is a. top plan view of the Fig. 8 is a perspective view of an element of the stripping mechanism.

The machine stands on a base consisting of two parts joined together by the frame member 16. Mounted upon thi base 15 and secured thereto by the stud bolts 29 are'the standards 28 with opposed guide faces '27 filled in at their lower part by a block '28. These guide standards '33 are joined across atthe top by the arching frame member 17 which spreads out at the mg Sheet-Metal Barrels. of which the folends as indicated by the reference numeral 30 and is fastened by the stud bolts 31.

The standards '28 carry on one side projecting journal brackets 18 in which is mounted the shaft 19 carrying a fly wheel 20 at its end. Locsely mounted upon this shaft 19 is the loose pulley 21 and the keyed driving pulley 22. At the other end of the shaft 19 is a spur gear pinion 23.

Also mounted upon this shaft 19 is the eccentric '21. The spur pinion :23 is engaged by the large gear wheel 25 on the shaft 26. \Vithin the guides 27 are vertical sliding blocks 3:2 which constitute journal bearings for the shaft 26. The frame members 30 have the vertical screw threaded shafts 33 therein. the lcwer ends of which act against the blocks 32 and the upper ends of which carry the adjusting hand wheels The shaft '26 carries the large longitudinally corrugated convex roll 35. seen in end elevation and section in Figs. 3 and 4. This roll is a single casting with sleeves 36 at'its ends. adapted to fit upon the shaft '26 and be secured in place by means of keys in the key ways 37. The shaft 26 also carries at opposite ends the beveled gear pinions 38.

The transverse frame member 16 has a block 10 at its middle which has bearings for the lower ends of the two oppositely inclined shafts 11 (see Fig. 2). The upper ends of these two shafts 41 have journal hearings in the blocks 4-1. which rest upon the tiller blocks '28 between the guides 27. The extremities of the shafts 41 carry beveled gear pinicns 12 in engagement with the respective pinions 38 on the shaft- 26. Each shaft 11 carries a tapering concave longitudinally corrugated roll 43. each such roll 43 being in engagement with the roll at one side of the equatorial line thereof.

The corrugations of theroll 35 are deeper at the ends than at the middle. The corrugations of the two rolls .43 are deeper at the smaller ends thereof. that is, the depth of the corrugations in the rolls 43 corresponds to the depth in the roll 35. The ratio of the radii at the outer ends of the rolls 35 and 43 is substantially the same as; the ratio of the radii of the roll 35 at its middle and of the roll 13 at itsinner end. But at intermediate points. this ratio is slightly different. However. the corrugations on the rolls do not intermesh exactly. enough play being left -to allow forslightly varying peripheral velocities of rotation of the .r'olls- The inner ends of the rollers 43' have beveled edge tracks 4,3 w ichroll together and thus take.

upthe end t rust on the shafts 41.

Th'e'eccentric strap 24 engages the eccentric 24 on the shaft 19 and connects by the eccentric rod 45 to the crank 46 loosely mounted on the shaft 47. This shaft 47 is supported by, journal brackets 47 attached to the guide standards 28: The shaft 47 carries a crank 50 and ja-ra-tchet wheel '48. The crank 46 r carries a pawl 49 that coacts with said i feed slide 58.

ratchet wheel 48 Connected to the crank 50 is'a link '51, the other extremity of which is pivoted to the bracket 59 .attached to the under side of the reciprocating The-feed table 52 has'upturned ears 53 at its. corners bolted to the guide standards'QS.

Angle irons 54 are attached to the side edges of the feed -ta-ble 52. to act as guides. Bracket-braces extend out from the main framework .of the machine to support the feed table 52. Attached to the underside of-the feed table 52 are guide lips 57 within which is the slide 58. The transverse angleuiron 606I lies on top-of the feed table 52, the flange 60 being turned up and. the flange 61 lying fiat on said table. This tlange (31 has slots 62 therein through which pass thc'stud screws 63 having the, parts 66 in engagement with holes in'the slide 58.

Each screw 63has an enlarged shoulder surrounded by a collar 64 lying within the slot 52 inthe table 52. I

, The radial webs 35' which extend out 'from'the sleeve parts 36 to support the corrugated con-vexroll '35 have enlarged porto'ry movement within the hole 67 being norinally' held outwardly by means of the "spring 70'. The collar 71 is corrugated continuously with the corrugations in the surfa'c'e' of the roll 35.- The projecting end 72 of the plug 69 is also corrugated so that "when the plug 69 is pushed down in its socket 67, these corrugations will be continuous with the corrugations of the roll 35 and the collar 71. Curved stripper guides 73 have their'upper ends attached to the cross frame member 17 and their lower ends in proximity to the surface of the convex roll 35. i

-By means-of the driving mechanism that has been described the rolls 35, 43, 43 are driven continuously from the drive pulley 22. The reciprocationsot the eccentric rod 45 cause the pawl 49 to rotate the ratchet heel 4d one tooth for each revolution of t" e shaft 19; The relation of the parts is such that the ratchet wheel 48 is rotated once for two complete revolutions of the drums and The rotation of the ratchet wheel 48 reciprocates the slide 58 in correspondence therewith. \Vhen the slide 5S-with its attached angle iron"606l is toward the end of the feed table 52 that is away from the machine, then the attendant lays a plane sheet of metal on the table 52 between the side guides 54 and before the angle iron.6061. Then as the ratchet wheel 48 continues to rotate, the sheet of metal is pushed ahead until its front edge is caught between the roll 35 and rolls 43. The relationof the gearing and the adjustment of the. slots 62 on the screws 63 is such that the piece of sheet metal operated upon is caught between the rolls so that its forwardedge comes just againstthe plungers 69-72. As [the rolls go around, these plungers are forced. back against the springs 70' by the rolls 43 and the piece of sheet metal is corrugated and bent to bilge shape. It would have a tendency to follow the roll 35 ar ound, but as soon as the forward edge gets through'from between the roll 35 and the rolls 43, then the springs 70 force said forward edge off from the roll 35 and a moment later this forward edge is caught by the lower extremities of the curved guides'..73. Then as the piece of sheet metal passeson between the rolls, it follows the guide 73, and finallvwhen it has passedclear through, it v falls from the rolls. As delivered from the rolls, the corrugated sheet-is not completely j curved in barrel shape, but itis an easy matter after the corrugations are made and the curve is started, to bend it around the rest of the way by hand. A slight degree of adjustment in the spacing of the rolls can be obtained by means of the hand wheels 34. Althoughthis would vary the relation of the gears a little, it would not be enough to do any harm. The machine will roll one sheet for every two revolutions of the rolls, the slide 58 being geared to reciprocate accordingly, and the attendant placing a sheet on said slide at each complete cycle of movement thereof.

It will be seen that the machine which has just been described is adapted to perform the objects already stated, but it is apparent that other devices within the scope of the following claims are comprehended within my invention.
